IMPROVED FAN ATTACHMENT TO SEWING-MACHINES.

Specification forming part of Letters Patent- No. 36,537,dated-.September 23, 1862.

To all whom it Amay conce-rn Be it known that I, WILLIAM T. SPENCE, ofSt. Louis, in the county of St. Louis and State of Missouri, haveinvented a new and Improved Fan Attachment for Sewing-Machines; and I dohereby declare that the following is a full,clear, and exact description,of the same, reference being had to the accompanying drawing, making apart of this specitcation, said drawing beinga perspective Vview ofmy-invention.

This invention consists in attaching a fan to the treadle of asewing-machine in such a manner that motion will-be given said fan bythe movement of the treadle in operating the sewing-machine, the deviceat the same time notinterfering with the proper opera-tion of any ot'the parts ofthe sewing-machine nor requiring any special Amanipulationof any kind.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents an upright bar which is attached to the top of the stand onwhich the sewing-machine is placed and secured. This upright is providedwith a base, B, through which screws pass into the top of the stand,said base having a hole, a, in it',"through which and a correspondinghole in the top of the stand a rod, C, passes, the latter being attachedto the treadle ot' the sewing-machine. In the upper end of the uprightbar A there is titteda lever, D, the lever being secured in a i'ork, b,in the upright by a fulcrnm-pin, c. The upper end of the rod C isconnected to the end of the lever D, and on the back part of said leverD, directly over its fnlcrum-pin c, there is a socket, d, in which thehandle ofl a fan, E, is inserted and secured by a set-screw, e, as shownclearly in the drawing. The fan E projects a suitable distance in frontof they upright bar A to be in a proper relative position with the faceof the operator.

From this description it will be seen that when the sewing-machine isoperated a vibratory motion will be communicated to the fan E, throughthe medium of the treadle ot' the machine and the rod C and acorresponding being ina p1 reci:tble. The cost of the fan attach-v mentwill be buttriilingpvhile in warm weather it will greatly relieve theoperator, especially if at work in a close or illy-ventilated apartment.

would remark that, if desired, the lever D may be placed in a reverseposition-.that is to say, project back of the uprightv bar A, instead ofinfront of it, and the rod C passes down back ofthe stand of themachine. This arrangement would avoid the cutting ot' a hole in the topof the stand for the rod C to pass through; but with the lever thusreversed it would be more exposed and would subject the machine togreater risk of being broken.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The lever and fan applied to a sewing-machine, and arranged so as to beoperated from the treadle thereof', substantially as herein set forth.

WILLIAM T. SPENGE.
